摘要

本文在由两个平行板组成的反应器中,利用正弦电源对常压下纯氮介质阻挡放电(DBD)进行一维模拟。为此,本工作通过考虑13种反应种的70多种反应,考虑了排放中反应种之间的重要反应。本研究中用于描述等离子体种动力学的模型是二阶流体模型,该模型包括用通量的漂移-扩散近似用前三个矩代替玻尔兹曼方程。为了验证本研究中建立的模型,在介绍等离子体种类性质的演变之前,将模拟的放电电流与现有的实验数据进行了比较。然后进行了参数化研究,显示了施加电压、频率和涂层介质材料性质等参数对氮中DBD特性的影响。最后给出了双介质DBD电抗器的仿真结果。

Modeling and parametric study of dielectric barrier discharge in pure nitrogen at atmospheric pressure
This paper presents the one-dimensional simulation of the dielectric barrier discharge (DBD) in pure nitrogen at atmospheric pressure using a sinusoidal supply, within a reactor which consists of two parallel plates. For this purpose, significant reactions among the reactive species in the discharge are taken into account in this work by considering more than 70 reactions for 13 species. The model used in this study to describe the kinetics of the plasma species is the second order fluid model which consists in replacing the Boltzmann equation by these first three moments by using the drift-diffusion approximation for flux. In order to validate the model developed in this research, a comparison of the simulated discharge currents obtained with available experimental data is carried out, before presenting the evolution of the properties of the plasma species. After that, a parametric study is performed showing the effect of some parameters like applied voltage, frequency and nature of the coating dielectric material on the characteristics of DBD in nitrogen. Simulation results for a double dielectric DBD reactor are also presented at the end of this paper.
